Frequently Asked Questions
What is API in One?
API in One is a unified AI API gateway that aggregates live AI models — including Flux 2, Kling, Suno, ElevenLabs, and Gemini — behind a single REST API. One API key, one credit balance, one consistent response format for image generation, video generation, music creation, text-to-speech, and chat.
How does billing work?
Credit usage is handled by the shared billing dashboard. Each live model route shows its current credit cost; buy or manage credits through the existing console.
Which models are supported?
Image generation (Flux 2, Kling Image, Ideogram), video generation (Kling 3.0, Seedance, Wan, Vidu, PixVerse, Hailuo, LTX, Grok Video), music generation (Suno), text-to-speech (ElevenLabs), chat and reasoning (Gemini), and AI tools (Face Swap, Background Removal). We continuously integrate the latest supported models as they launch.
Do I need a separate key for each model?
Use your API in One key for routed models and specify the supported model name in your JSON body.
